20090105103 | Lubricating Oil Composition - A lubricating oil composition for use in oil-impregnated sintered bearings together with a resin member having C═C bonds or C═O groups in the molecules, which comprises a base oil comprising a synthetic hydrocarbon oil as the main component, and 0.1-30% by weight of an ester-based oil on the basis of total composition, and free from zinc dialkyldithiophosphate and molybdenum dialkyldithiocarbamate, where the synthetic hydrocarbon oil as the main component of the base oil has substantially no adverse effect on resin, can minimize an adverse effect on various metal species of sintered materials by suppressing a mixing amount of a wear inhibitor or an extreme pressure agent to a minimum, without deteriorating a good lubricability required for the lubricating oil in oil-impregnated sintered bearings. | 04-23-2009 |
20090270291 | Wet Lubricant Surface Coating Having Excellent Durability, Method for Surface Coating, and a Medical Device Having The Surface Coating - A lubricant surface coating having good lubricity and high durability, comprising (A) an urethane polymer layer comprising (a) 40 to 80% by weight of at least one component selected from an aromatic diisocyanate, an aliphatic diisocyanate and an alicyclic diisocyanate and (b) 20 to 60% by weight of a polyol having at least trifunctionality and (B) a hydrophilic polymer layer provided as the outer layer for the urethane polymer layer which comprises a polyalkylene glycol and/or a monomethoxypolyalkylene glycol; and a medical device having the surface coating. | 10-29-2009 |
20100029521 | GREASE COMPOSITION AND MACHINE ELEMENTS - A grease composition which contains a large amount of thickener, and may prevent a flaking effectively for a long period of time, and machine elements in which the grease composition is filled are provided. A grease composition comprising a thickener and a base oil, characterized in that the thickener contains a diurea compound represented by the Formula (I): | 02-04-2010 |
20120028859 | METHOD OF PREPARING GREASES - Provided is a method for preparing a grease composition, which comprises mixing an amine in a lubricating bas oil and an isocyanate in a lubricating base oil under high pressure and high flow rate impingement. In one embodiment, the mixing and reaction occurs in a reaction injection molding device. The resulting grease composition is an extremely low noise grease, being virtually clear of any urea thickener particles. | 02-02-2012 |
20120028860 | Method of Preparing Greases - Provided is a method for preparing a grease composition, which comprises mixing grease components under high pressure and high flow rate impingement. In one embodiment, a first mixture of an amine in a lubricating base oil is mixed with an isocyanate in a lubricating base oil under high pressure and high flow impingement. In another embodiment, the mixing and reaction occurs in a reaction injection molding device. The orifice size through which each of the mixtures is introduced into a reaction/mixing zone is less than 0.030 inch (0.0762 centimeter) in diameter. The resulting grease composition is an extremely low noise grease, being virtually clear of any urea thickener particles, and/or can exhibit good high temperature resistance and mechanical stability. | 02-02-2012 |
20130040868 | RESIN COMPOSITION WHOSE LUBRICITY UNDER WET CONDITIONS IS MAINTAINED - Provided is a resin composition which has excellent lubricity and a good touch feeling under wet conditions and suffers from little deterioration in the lubricity or the good touch feeling even if used repeatedly, and is excellent in flexibility. More specifically, the resin composition contains 100 parts by mass of a water-absorbing polymer and 60 to 500 parts by mass of a thermoplastic resin that has a type D durometer hardness (HDD) of 10 to 60. | 02-14-2013 |
20150299608 | GREASE COMPOSITION FOR HUB UNIT BEARING - The invention provides a grease composition for hub unit bearing, having (a) as a base oil a mixture of a hydrocarbon synthetic oil and an ester type synthetic oil, with the content of the ester type synthetic oil being 20 to 50 parts by mass with respect to 100 parts by mass of the total of the hydrocarbon synthetic oil and the ester type synthetic oil, and the base oil having a kinematic viscosity at 40° C. of 20 to 80 mm | 10-22-2015 |
